Title: Linear beam microwave tube
Inventor: UEDA ISAO
IPC: H01J23/027
Filed: 1978-03-13
Abstract: PURPOSE: To obtain a linear electron beam microwave tube possessing the collector featuring the reduced retrograde secondary electron generation with the facilitated manufacturing process by providing the collector which is formed into a polygon with soldering of the panel-type component.  
     CONSTITUTION: Collector part 10 includes collector 11 and cooling tank 12, and collector 11 is cooled down by cooling water 13 stored in tank 12 via the evaporation cooling system. Collector 11 contains rectangular inner side surfaces 22W25 which are formed into a body at soldering part 21 and through combination of the panel- type component. Groove 27 is cut at the outer side of the panel-type component to increase the efficiency of the evaporation cooling. With this rectangular collector, the electron motion of the collector has no synchronization under the specified conditions but always features random. Thus, the sudden increment of the secondary electron or occurrence of  the parasitic oscillation and others can be avoided within the collector under the specified conditions of the incident level of the primary electron or the focusing magnetic field. Furthermore, the coating process and the shape formation can be facilitated for the surface to suppress the secondary electron because of the collector composition by the panel-type component.

Title: Electron tube including photoelectric surface capable of performing gate operations at low voltage
Inventor: MORI HIROSHIGE
IPC: H01J43/02
Filed: 1988-02-10
Abstract: PURPOSE:To make it possible to perform gate operations at low voltage, thereby allow the switch-over of a gate to be made sharply by restraining the emission of electrons in such a way that gate voltage is applied between a conductive material and a photoelectric surface via an insulating thin film. CONSTITUTION:A power supply E2 is kept regulated at appropriate voltage, then, when a light comes in through the glass window 19 of a vacuum hermetic container, a conductive thin film 11 and an insulating thin film 13 with a power supply E1 kept zero volt, photoelectrons are emitted from a photoelectric surface 15. Then, they are accelerated by the electric field formed by the power supply E2 so as to be arrested by an electron collecting electrode 17 so that they are inputted as electric signals. In the second place, when the power supply E1 is increased in voltage so as to make the electric potential of the conductive thin film 11 positive against the photoelectric surface 15, the emission itself of photoelectrons is restrained. Voltage generated can be made fairly lower than the difference in electrical potential applied between the photoelectric surface and an anode, which is different depending on the thickness of the insulating film and the kind of the photoelectric surface though because voltage is directly applied to the photoelectric surface 15. This constitution thereby enables a low voltage drive circuit to perform gate operations.

IPC: H04M11/00
Filed: 1994-02-28
Abstract: PURPOSE:To reduce a procedure time without use of a polarity inversion detection circuit by allowing the facsimile equipment to transit to a signal judging processing judging a procedure signal sent at a high speed when a high speed procedure confirm signal is detected as a response signal. CONSTITUTION:A sender side facsimile equipment sends a high speed procedure instruction signal (SNSS) just after dialing to start a timer and sends again the SNSS when no called station response signal is detected after lapse of a time T1 and judges again whether or not the reception side sends a response signal till the time T1 elapses. On the other hand, when the called station response signal is detected, whether or not the response signal is a high speed procedure confirm signal (SNSF) is judged and when the signal is the SNSF, the facsimile equipment transits to the signal judgement processing judging the high speed procedure, that is, the procedure signal sent at a high speed. Furthermore, when the response signal is not the SNSF, the facsimile equipment transists to the signal judgement processing judging the usual procedure, that is, the procedure signal sent at a usual speed.

Abstract: PURPOSE:To facilitate the small-sized and lightweight formation and secure the high compression efficiency at a low cost by constituting the movable and fixed scroll members from only the movable and fixed swirl bodies and applying fluorinated resin onto one of the opposed surfaces of the both swirl bodies and applying hard alumite onto the other. CONSTITUTION:A movable scroll member is constituted only of a movable swirl body 20, and a fixed scroll member is constituted of only a fixed swirl body 22. The main function of a plate body which is provided by the scroll member in the conventional is developed by the plane parts of the first and second closing plates 30 and 32 opposed to the both edge surfaces of the movable and fixed swirl bodies 20 and 22. Therefore, the plate body which was necessary in the conventional type can be removed. Further, one of the opposed surfaces of the movable and fixed swirl bodies 20 and 22 which form a sealed space is coated with fluorinated resin, and the other is coated with hard alumite, and therefore, even if no clearance is formed therebetween, fluorine scrapes the hard alumite during operation, and thereafter an ideal clearance of nearly zero can be kept.
